Abstract

An investigation was carried out on the effect of physical aging on viscoelastic properties of compatible polymer blends. Poly(methyl methacrylate)(PMMA) and poly(styrene-co-acrylonitrile) (SAN) were chosen for this study. Blends of six different ratios of PMMA and SAN were physically aged at different times and temperatures and then subjected to stress-relaxation tests at small strains. It was found that the shape of the stress-relaxation curve does not change with a change in blend composition, aging temperature, or aging time. For a given set of experimental conditions, the relaxation time τ may be expressed in terms of blend composition, aging temperature, and aging time.
